### setOutputVolume

* **setOutputVolume**(`params`): `Promise<void>`

    ID of the member to affect.
  </ParamField>

    Desired volume. Values range from -50 to 50.
  </ParamField>

#### Returns

`Promise<void>`

#### Example

In this example, we wait for a room to start and then wait for a member to join the room.
When a member joins the room, we set the output volume for that member to -50.
This example assumes that there is a [`RoomSession`][roomsession-41]
already active and that members are joining the room.

```js
import { SignalWire } from "@signalwire/realtime-api";

// Initialize the SignalWire client
const client = await SignalWire({ project: "ProjectID Here", token: "Token Here" });

// Access video client from the main client
const videoClient = client.video;

// Setup listener for when a room starts
await videoClient.listen({
  onRoomStarted: async (roomsession) => {

    console.log("Room started", roomsession.displayName);

    roomsession.listen({
      onMemberJoined: async (member) => {
        console.log("Member joined", member.displayName);
         // set output volume to -50dB
         console.log("Setting output volume to -50dB for", member.name);
        await roomsession.setOutputVolume({
          volume: -50,
          memberId: member.id
        });
      },
      onMemberUpdated: async (member) => {
        console.log(`${member.name} output volume is now ${member.outputVolume}`);
      },
    })
  }
});
```
